In the figures, the same components are identified by the same reference numerals.

In FIGS. 1 to 11, a container such as, for example, one which may be used for storing ice cubes, ice chips, crushed ice, ice fragments or the like, or for any suitable purpose such as, for example, the storage of any type of edible or non-edible matter, comprising a container basin 11 and a container handle 12. The container basin 11 may comprise any suitable material such as, for example, aluminum or plastic or any suitable natural or artificial material, in any suitable configuration as a receptacle, bucket, tub, basin or the like. The container handle 12 may comprise any suitable material such as, for example, metal, in any suitable configuration such as, for example, an inverted U-shape, having a substantially uniform cross sectional diameter.

The container basin 11 may include a similarly shaped, but slightly smaller-dimensioned, basin portion 13 of suitable material such as, fare example, plastic or glass, positioned snugly inside said container basin with a suitable heat insulating device or heat insulation 14 positioned between said container basin and said basin portion (FIG. 10). A suitable heat insulating device or heat insulation may comprise, for example, reflecting or mirrored surfaces or Fiberglas insulation in sheet form. The container is then especially useful as an ice bucket for storing ice cubes, crushed ice or any other substance which must or should preferably be kept cold or hot.

The container handle 12 is pivotally afiixed to the container basin 11 by any suitable means such as, for example, a pivot pin, rivet, bolt or the like 15 which pivotally fastens one leg 12a of the inverted U-shaped container handle to one side of said container basin and a pivot pin, rivet, bolt or the like 16 which pivotally fastens the other leg 12b of said container handle to the opposite side of said container basin.

The free-sliding guide device of the present invention enables the container cover 17 to be slidable and to be retained on the handle 12 of the container while remaining free of the container basin 11 and while permitting free access to said container basin. The container cover is self-closing when the container handle is in its substantially vertical position due to gravity pull on said cover. One embodiment of the free-sliding guide device of the present invention comprises two pairs of spaced guide projections extending from the container cover 17 on opposite sides of said container cover.

The first pair of the two pairs of spaced guide projections preferably comprises a pair of substantially spherical projections 18a and 18b and the second pair of said pairs of spaced guide projections preferably comprises a pair of substantially spherical projections 19a and 19b.

The first and second pairs of guide projections 18a, 18b and 19a, 1% are affixed to opposite sides of the peripheral surface 17a of the container cover 17. In the embodiment of FIG. 1, the container cover 17 is round and has a substantially constant diameter and a substantially cylindrical peripheral surface 17a, so that in the embodiment of FIG. 1, the first and second pairs of guide projections are positioned on said container cover at diametrically opposite areas on said peripheral surface.

Each of the spherical guide projections 18a, 13b, 19a and 19b is aifixed to the peripheral surface 17a of the container cover 17 by any suitable fastening means such as, for example, a rivet, a bolt, a pin, a weld or the like. Each of the spherical guide projections 18a, 18b, 19a and 19b is preferably tangentially afiixed to the peripheral surface 17a, although such may not necessarily be the case where each of the guide projections is semior hemispherical in configuration. The diameter of each of the guide projections 18a, 18b, 19a and 1912 may be larger or smaller than the diameter or thickness of the leg of the container handle.

The guide projections 18a and 18b of the first pair of guide projections extend on diametrically opposite sides of the corresponding portion or leg 12a of the container handle 12 and are spaced from each other a distance D slightly greater than the thickness or diameter of said leg of said container handle.

The guide projections 18a, 18b, 19a and 1912 need not be of spherical configuration, but may comprise any suitable projections extending from the container cover 17. The guide projections may be afiixed to the peripheral surface 17a or to any other suitable part of the container cover 17. Suitable guide projections may comprise, for example, pins or prong-like components 21a, 21b and 22a, 22b which may be atfixed t0 the container cover 17 by any suitable fastening means or which may be integrally formed with said container cover (FIG. 3).

The container cover 17 may be of any desired configuration, as may the container basin 11. Usually, the opening or mouth of the container basin 11 corresponds in configuration with the shape of the peripheral surface 17a of the container cover 17. Thus, the container cover 17 and the mouth of the container basin 11 may have any desired configuration such as, for example, a polygon. A suitable container cover configuration may be a square, as shown in FIG. 4, wherein the container cover 17' and its pehirpheral surface (not shown) are of substantially square configuration. The guide projections 18a, 18b and 19a, 191') are identical with the guide projections 18a, 18b and 19a, 19b and are positioned on opposite sides of the container cover 17'. The projections of each pair of guide projections 18a, 18b and 19a, 19b are spaced from each other the distance D, which is slightly greater than the thickness or diameter of the container handle 12 (not shown in FIG. 4).

The container cover 17 may have a knob 23 of any suitable type or style or configuration affixed to the axial center of said container cover or integrally formed with said container cover. In the embodiment of FIG. 1, the knob 23 is of substantially frustoconical configuration with the smaller diameter surface abutting the cover 17. In the embodiment of FIG. 4, the knob 23' is of substantially frustopyramidal con-figuration with the smaller surface abutting the container cover 17.

i In operation, when it is desired to introduce or remove matter or material such as, for example, ice cubes or crushed ice, into or from the container basin 11, the container cover 17 is manually lifted via the knob 23 thereof and raised out of contact with said container basin (FIG. 7). Since matter is more easily introduced into and removed from the container basin 11 when the opening or mouth thereof is completely exposed, it is desirable to completely remove the container cover 17 from said mouth and to move the container handle 12 clockwise or counterclockwise (as shown in FIGS. 7, 8 and 9) so that it lies in a position (FIG. 9) where its does not obstruct said mouth in the least.

Thus, as soon as the container cover 17 is lifted off the container basin 11., the container handle 12 is manually pivoted to a position where its does not obstruct the mouth of said container basin. As the container handle 12 is pivotally moved, the container cover 17 is manually moved along the legs of said container handle in a direction away from the container basin 11. As it is moved, the container cover 17 slides readily and facilely along the legs of the container handle 12 due to the action of the guide projections lea, 18b and 19a, 19b. The guide projections 13a, 18b and 19a, 19b maintain the container cover 17 on the container handle 12 and the guide projections 18a and 1% contact said container handle and facilitate the sliding movement of said container cover along the legs of said container handle.

The guide projections 18a, 18b and 19a, 1% may each be pivotally mounted on the container cover 17 or they may be fixedly mounted on said container cover. The guide projections 18a, 18's and 19a, 1912 may be separated from each other by the distance d, which is slightly greater than the thickness or diameter of the container handle 12.

When the container handle 12 is pivotally moved in a counterclockwise direction, the guide projections 18!) and 1% contact said container handle and facilitate the sliding movement of the container cover 17 along the legs of said container handle. When the container handle 12 is pivotally moved in a clockwise direction, as shown in FIGS. 8 and 9, the guide projections 18a and 19a contact said container handle and facilitate the sliding movement of the container cover 17 along the legs of said container handle.

If the container handle 12 is pivotally moved to a great enough angle with the vertical, the container handle 12 and the container cover 17 will remain in positions in which they do not obstruct the mouth of the container basin 11 and in which they will rest, so that both hands of the user are then free to execute the desired operation of introducing material into or removing material from said container basin. The container cover 17 always remains on the container handle 12 so that it is never misplaced and is rapidly, readily and facilely replaced on the container basin 11 to cover the mouth of said container basin when it is desired to do so. This is accomplished by moving the container handle 12 to a substantially vertical position and either moving the container cover 17 into engagement with the container basin 11 or permitting said container cover to move by gravity into engagement with said container basin.

The container cover 17 may be positioned in slidable engagement with the container handle 12 by any suitable means. Thus, for example, utilizing the view of FIG. 5 as an illustration, the container cover 17 may be readily positioned on or removed from the container handle 12 by moving the first pair of guide projections 18a and 18b away from or toward the container basin 11 and at the same time respectively moving the second pair of guide projections 19:: and 1% toward or away from said container basin.

FIG. 11 illustrates an embodiment of a position locking device of the present invention which may be utilized with the embodiment of FIG. 1. The position locking device comprises an arm 24 and may also comprise an additional, identical arm 25, if desired. The arm 24 is a bridge across the distance between the guide projections 18a and 18b and/ or 19a and 19b and abuts the leg 12a of the container handle 12. The arm 24 may comprise any suitable material such as, for example, metal, which by abutting the leg of the handle of the container holds the cover 17 in position wherever it may be on said handle. The position locking device is preferably somewhat permanently afiixed in position. The arm may be substantially C or U-shaped and may be removably or resilient to permit the free sliding of the cover 17 along the handle 12 and yet insure that the pressure of the arm 24 and/ or 25 will hold the cover in its position when manual force is removed.

In FIGS. 12 to 16, a container, similar to that of FIGS. 1 to 11, comprises a container basin 31, similar to the basin 11, and a container handle 32, 33. The container handle 32, 33 may comprise any suitable material such as, for example, metal, in any suitable configuration such as, for example, an inverted U-shape of split leg type, having spaced substantially parallel extending members 32a and 33a comprising one leg and spaced substantially parallel extending members 32b and 33b comprising the other leg (FIGS. 14, 15 and 16). The container handle 32, 33 may comprise two similar U-shaped members (FIGS. 14 and 15) parallel positioned at an equal distance from each. other and pivotally mounted on the container basin 31 or a handle having spaced substantially parallel extending members for legs and a solid, one-piece hand or gripping portion (FIG. 16). The extending member 33a is not shown in the drawing because of the views of the container shown. The handle may be slotted to provide the spaced parallel extending members for the entire length or a portion of the length of its legs.

The container handle 32, 33 is pivotally affixed to the container basin 31 by any suitable means such as, for example, a pivot pin, rivet, bolt or the like 34 which pivotally fastens one leg 32a, 33a of the inverted double U-shaped container handle to one side of the container basin and a pivot pin, rivet, bolt or the like 35 which pivotally fastens the other leg 32!), 33b of said container handle to the opposite side of said container basin.

The free-sliding guide device of FIGS. 12 to 16 of the present invention enables the container covers 36 to be slidable and to be retained on the handle 32 33 of the container while remaining free of the container basin II and while permitting free access to said container basin. The embodiment of FIGS. 12 to 16 of the present invention comprises a pair of spaced guide projections extending from the container cover 36 on opposite sides of said container cover.

The first of the pair of spaced guide projections preferably comprises a pin or prong-like projection 37 and the second of said pair of spaced guide projections preferably comprises a pin or prong-like projection 38. The first and second guide projections 37 and 38 are 'afiixed to opposite sides of the peripheral surface 36a of the container cover 36. The container cover 36 is similar to the container cover 17, and the first and second guide projections are positioned on the container cover at diametrically opposite areas on the peripheral surface 36a.

Each of the guide projections 37 and 33 may be affixed to the peripheral surface 36a of the container cover 36 by any suitable fastening means such as, for example, a rivet, a weld, a nut or the like. Each of the guide projections 37 and 38 preferably extends substantially perpendicularly or diametrically from the peripheral surface 36a of the container cover 36. The diameter of each of the guide projections 37 and 38 is slightly smaller than the distance between the spaced parallel extending members 32a, 33a and 32b, 33b of the legs of the handle 32, 33.

The guide projections 37 and 38 may be affixed to the peripheral surface 36a or to any other suitable part of the container cover 36. The container cover 36 is similar to the container cover 17 or 17' and, as such covers may be, may be of any desired configuration. The container cover 36 may have a knob 39 which is similar to the knob 23 or 23.

The spaced parallel extending members 32a and 33a of one leg of the handle 32, 33 are spaced from each other a distance S, which is slightly greater than the thickness or diameter of the guide projection 37. The spaced parallel extending members 32b and 33b of the other leg of the handle 32, 33 are spaced from each other the distance S, which is slightly greater than the thickness 01 diameter of the guide projection 38.

A stop member 41 is preferably positioned between the spaced parallel extending members 32!) and 33b of the handle 32, 33 and any suitable stop device to prevent excessive movement of the container cover such as, for example, a similarly positioned stop member (not shown) may be positioned where desired and is preferably positioned between the spaced parellel extending members 32a and 33a. The stop members prevent the container cover from sliding beyond the points of said stop members. In the modification of FIG. 16, the container handle 32', 33' is similar to the container handle 32, 33 except that it is provided with a solid one-piece hand or gripping portion 42 which also serves as the stop member.

The operation of the embodiment of FIGS. 12 to 16 is essentially the same as that of the embodiments of FIGS. 1 to 11, except that, as it is moved, the container cover 36 slides readily and facilely along either the members 32a and 32b of the legs of the container handle 32, 33 or the members 33a and 33b of the legs of said container handle. The guide projections 37 and 38 maintain the container cover 36 on the container handle 32, 33 and said guide projections contact either the members 32a and 32b, respectively, or the members 32a and 33!), respectively and facilitate the sliding movement of said container cover along the legs of said container handle.

The container cover 36 may be positioned in slidable engagement with the container handle 32, 33 by any suitable means. Thus, for example, in a manner essentially similar to that of the cover 17, the cover 36 may be readily positioned on or removed from the container handle 32, 33 by moving the first guide projection 37 away from or toward the container basin 31 and at the same time respectively moving the second guide projection 38 toward or away from said container basin.

FIGS. 17 and 18 illustrate an embodiment of a position locking device of the present invention which may be utilized with the embodiment of FIG. 12, modified as indicated in said figs. The position locking device comprises an internally threaded post or hollow rivet-like sleeve 45 having a head 46 positioned in an aperture formed through the peripheral surface 36a of the container cover 36 and having an axial length which does not extend to the farthest part of the surface of the parallel extending members 32a, 33a and 32b, 33b from said container cover. The diameter of the sleeve 45 is less than the distance S between corresponding parallel extending members. A threaded member 47 having a knurled head 48, which may be channeled for rotation with a screw driver but which is preferably knurled for manual rotation, is threadedly engaged in the sleeve 45.

The sleeve 45 extends substantially perpendicularly from the peripheral surface 36a of the container cover 36 and passes into the space S between the parallel extending members of the corresponding leg of the container handle 32, 33. Thus, when the container cover 36 is at a desired position above the container 31 or on said container, the screw 47 may be rotated and tightened in the sleeve 45 until the head 48 abuts the parallel extending members 32b and 33b with sufiicient force to hold or lock said container cover in position. A single unit, 45, 46, 47, 48 as shown, may be utilized. However, a pair of locking units 45, 46, 47, 48, diametrically oppositely positioned, may be utilized as a modification of the embodiment of FIG. 12.

While the invention has been described by means of specific examples and in specific embodiments, I do not wish to be limited thereto, for obvious modifications will occur to those skilled in the art without departing from the spirit and scope of the invention.
